Stainless Steel Wire Mesh Pleated Cartridge
Increasing Filtration Area and Improve Filter Efficiency

The pleated metal filter element are constructed with supporting layers and filter layer, pleated then welded together. With a supporting layer, it could undertake the high pressure. With the pleated process, it increases the filtration area several times more than the usual candle filter. Because of this, pleated metal filter element shortens the filter time and improves the filter effectiveness.

It’s an ideal material for polymer metal filter element on fibers, films and resins. It’s also widely used for chemical fiber, textiles and plastic industries. We design a range of products to meet the diverse filtration, separation, and purification demand


  • High flow rates. The pleated process increases the filter area and dirt holding capacity. The pleated metal filter element reduces the differential pressure and saves the filter cost.
  • Long on-stream life time. The pleated metal filter element has supporting layer to protect the filter layer avoiding being destroyed. Besides, when customer install in their equipment, there’s perforated tube inside or outside to protect the pleated metal filter element. These help extends the lifespan, reduce downtime and save cost.
  • Easy to clean. TPleated filter element can be washed by superheated steam, chemical, Ultrasonic and other methods to remove the contamination. We have a skilled technical department to solve the critical cleaning problems to extend the filter on-stream lifetime. If you have any quesitons, pls contact us.
